          ----------
          mol2_lines : list
              A list of lines containing the mol2 file contents. For example,
              ['@<TRIPOS>MOLECULE\n',
               'ZINC38611810\n',
               '   65    68     0     0     0\n',
               'SMALL\n',
               'NO_CHARGES\n',
               '\n',
               '@<TRIPOS>ATOM\n',
               '      1 C1  -1.1786  2.7011  -4.0323 C.3  1 <0>   -0.1537\n',
               '      2 C2  -1.2950  1.2442  -3.5798 C.3  1 <0>   -0.1156\n',
               ...]
  
          mol2_code : str or None
              Name or ID of the molecule.
  
          columns : dict or None (default: None)
              If None, this methods expects a 9-column ATOM section that contains
              the following columns:
              {0:('atom_id', int), 1:('atom_name', str),
               2:('x', float), 3:('y', float), 4:('z', float),
               5:('atom_type', str), 6:('subst_id', int),
               7:('subst_name', str), 8:('charge', float)}
              If your Mol2 files are formatted differently, you can provide your
              own column_mapping dictionary in a format similar to the one above.
              However, note that not all assert_raise_message methods may be
              supported then.
